Senior Mechanical Engineer

Orbital uses AI to build data center hardware that outperforms the competition. Our AI simulates materials at the atomic level, tests millions of hardware configurations in the time traditional methods test hundreds and finds optimal designs - not just good ones. The result is shipped hardware with specs incumbents can't match.

Every deployment generates field data that improves our AI models. Better models produce better hardware. Better hardware enables more capable AI. The loop is already closed and tightening with each build cycle. We are not just beneficiaries of AI progress, we are a lever on its rate.

Data Centers are where we start, because the market is urgent and the specs are demanding. But the AI-accelerated development process we've built - materials discovery, hardware design, manufacturing optimization - applies to any complex physical system. Data Centers are the proof point, not the ceiling.

We have sites in London, Canada and the USA, building teams across ML research, Product development, Mechanical engineering, and Chemical engineering. If you want to work where AI meets atoms, we'd like to hear from you.

Orbital Materials is seeking a highly skilled and innovative Senior Mechanical Engineer to design and optimize advanced modular data centers, focusing on revolutionary two-phase direct-to-chip cooling applications leveraging Orbital's proprietary fluid discoveries, and developing dual-use chiller systems for simultaneous data center cooling and carbon capture.

This role involves hands-on participation in cutting-edge research, including design and layout of mechanical systems for data center equipment and actively participating in and conducting lab experiments to verify the validity and performance of our modular data centers, novel cooling solutions and integrated carbon capture systems.
